Transformation mixins breaking valid CSS code.

The Transformation mixins such as scale, translate, etc... were all breaking their normal CSS counterparts. Because of transparent mixins and what not in Stylus, with a rule such as:
transform: scale(1)
You'd end up getting something along the lines of:
transform: transform: scale(1);;
Removing the usage of the translate mixin.

Was only used in .modal-dialog for transitioning.
